RFV SPLIT is connected as follows. (See corresponding
Installation and Maintenance Instructions for terminal
block positions.)
SPLIT All-in-one
F -> Terminal block X4, 2*
G -> Terminal block X4, 1*
H -> Terminal block X4, 3*
Adjustment during installation
The room sensor is primarily intended to correct decreases
in room temperature due to causes other than changes
in the outdoor temperature, for example, centralised load
control.
The room sensor corrects the curve slope so that the flow
temperature changes. If the room temperature changes
the room sensor senses this and lets the processor change
the flow temperature.
Any radiator valves ought to be fully open in areas where
the room sensor is installed.
Activation
RVF SPLIT must be activated in the menu.

External control of the room tem-
perature, extra option
The room temperature can be altered between two pre-
set values. If the room sensor connection is supplement-
ed with an external potential free contact function, for
example telephone switch or clock, the preset values can
be used. When the contact function is made the room
sensor is connected and influences the flow temperature.
Example: The basic setting gives a specific flow tempera-
ture. The room sensor is set to a lower temperature. When
the contact is made, the lower temperature applies until
the contact will be broken again.
Connection to be done on terminal block 14/X1/X4 in all before mentioned heat
pumps and electric boilers. Note that connection to Split All-in-one must be carried
out according to section "Connecting external contacts" in the product's Installation
and Maintenance instructions.
